The non-structural grades are where weldability gets a bit gray. These are often referred to as low carbon nuts, and little attention is paid to their specific chemistry. In a random sampling of numerous sizes of nuts in our inventory, representing five different manufacturers, it appears that smaller nuts, those 1? and below, are cold formed and made from 1008 or 1010 steel, which has low carbon, low manganese, and would chemically be considered weldable. Above 1? diameter however, the nuts are hot formed and are made from medium carbon steel similar to AISI 1045.
